The HDMI DDC driver for both mt7623 and mt8167 is actually the same as
mt8173-hdmi-ddc and the mt7623n.dtsi board include file already uses
mt8173-hdmi-ddc compatible as a fallback, but the documentation lists
them as separate entries. Correct the binding by adding the correct
fallback.

Fixes the following dtbs_check error in mt7623n-rfb-emmc.dts and
mt7623n-bananapi-bpi-r2.dts:
i2c@11013000 (mediatek,mt7623-hdmi-ddc): compatible:
['mediatek,mt7623-hdmi-ddc', 'mediatek,mt8173-hdmi-ddc'] is too long
